Polymarket Edge Tracker

polymarket_edge_tracker
Read-onlyIdempotent

Edge persistence and decay telemetry built from daily polymarket_edges snapshots. Answers "how long has this edge existed and is it shrinking?" — a fresh wide edge and a 3-week-old wide edge are different trades (the latter is wide for a reason nobody is willing to take). Args: days (lookback, default 14, max 30), window (snapshot family, default "1wk"). RESPONSE: tracked[] = every opportunity in the LATEST snapshot with its full edge_pp_net time-series across prior snapshots, first_seen, trend (new | widening | stable | decaying) and decay_pp_per_day (both computed on |edge_pp_net| — the value itself is signed by trade direction, negative = SELL YES); expired[] = opportunities that appeared in earlier snapshots but are GONE from the latest (closed, resolved, or arbed away) with their lifespan_days — the median lifespan is your competition clock; snapshot_dates[] = which days actually have data (snapshots are written when polymarket_edges runs on a cache-miss, so gaps mean nobody scanned that day). LIMITS: history depth is bounded by the 60-day snapshot TTL and starts from when snapshotting was enabled; decay numbers come from daily closes of edge_pp_net (net of default slippage), not intraday.

A4.1/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, so the description does not need to repeat safety. It adds useful behavioral details: how trends and decay are computed, that snapshots are daily with gaps, and the 60-day TTL limitation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is dense and front-loaded with purpose, but it is verbose and could be more concise. It contains multiple clauses and details that, while informative, could be streamlined for quicker comprehension.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description compensates for the lack of output schema by thoroughly explaining the response structure: tracked[], expired[], snapshot_dates[]. It also describes limitations and data sources, providing a complete picture for a data retrieval tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the description adds default values and explains the effect of 'days' (lookback) and 'window' (snapshot family). This provides marginal value beyond the schema, but does not significantly enhance understanding of parameter semantics.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool's purpose: providing edge persistence and decay telemetry from daily snapshots, answering 'how long has this edge existed and is it shrinking?'. It uses specific verbs like 'tracked', 'expired', and distinguishes from the sibling 'polymarket_edges' by focusing on time-series and decay.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool is for historical analysis of edge persistence but does not explicitly state when to use it versus alternatives or provide exclusions. The context is clear but lacks direct guidance on when-not-to-use or comparisons with siblings.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A4.1/5.0
Disambiguation4/5

Most tools have distinct purposes with clear descriptions, but ask_pipeworx_beta is nearly identical to ask_pipeworx, and the presence of several meta-tools may cause slight confusion. Overall, an agent can differentiate most tools.

Naming Consistency4/5

Tool names consistently use lowercase_with_underscores and follow an action_domain pattern (e.g., validate_claim, scan_competitor_ai_presence). There is a mix of verb-noun and noun-verb, but the pattern is predictable and readable.

Tool Count3/5

33 tools is on the higher end, but given the broad scope (finance, drugs, prediction markets, data retrieval, memory), the count is reasonable. However, the server name 'Hurricanes' suggests a narrower focus, making the count feel excessive for that domain.

Completeness4/5

The tool set covers a wide range of data domains and includes meta-tools for discovery, grounded answers, and subscriptions. Minor gaps exist (e.g., no non-US company data), but overall the surface is comprehensive for a general-purpose data server.
